| onmousemove is, by default, not an event of any object, because mouse movement happens very frequently. onmousemove在預設情況下不是任何一個對象的事件，因為滑鼠是頻繁移動的。 |
Note: Each time a user moves the mouse one pixel, a mousemove event occurs. It takes system resources to process all mousemove events. Use this event carefully!
注意：當使用者滑鼠移動一像素時，就會觸發一次mousemove事件。這將非常消耗系統的資源，請謹慎使用。
